I would like someone could help me to configure a SIP Trunk.
I have to connect a CUCM 9.1 to a VoIP service provider. This SP have send me the next informatio.
a Host name of the SIP Trunk
a User and Password.
I have nerver configured a sip trunk with authentication in CUCM so I have investigated about it and I'd tried to configure myself.
I have tested CUCM ping the SP sip trunk IP.
I'd created a SIP trunk to the SP trunk sip IP in CUCM.
I create a new security profile and check "digest credentials"
I created a SIP realm with the next information.
realm: ip of the SP trunk sip. ( I dont have DNS configured in CUCM and I use the IP here, it is rght?)
User: user SP provided me.
Password: password SP provide me.
So I don' t know if I need enything else
It is not working anyway,
